581. The deterioration of milking rubbers: V. The effect of rubber composition

Abstract

The importance of fat absorption as a cause of deterioration in the rubber teat-cup liners of milking machines has already been demonstrated (l, 2), and it is well known that the composition of the rubber affects its resistance to fat. It was considered desirable, therefore, to see what changes in composition could usefully be made, and how these would affect fat absorption under normal milking conditions. To this end, and with the cooperation of a large number of farms and Milk Production Officers, the four experiments reported here were carried out.
